Immunofluorescence assay of caspase and Ki-67 expression in the tumor areas (400×). Images of tumor tissues isolated from PBS-, EcN-, EcN (p53)-, EcN (Tum-5)-, or EcN (Tum 5-p53)-treated BALB/c nude mice bearing SMMC-7721 tumors, which were stained for caspase-3 (a) and Ki-67 (b) after intravenous injection, and the cell nucleus is stained in blue (Hoechst). Quantitative analysis of caspase-3 (c) and Ki67 (d) positive cells in the tumor areas of mice in each group (*P<0.05)
